Fusion and syncytium formation induced by the expression of fusogenic viral glycoproteins are common cytopathic effects. Numerous laboratories have studied mechanisms of fusion, generally with each laboratory utilizing a different method to measure polykaryote formation. There is little consensus as to which methods are preferred for measuring and comparing fusion. The Kolmogorov-Smirnov two-sample test was used to document a statistical difference in syncytium formation between two forms of a varicella-zoster virus (VZV) fusogenic glycoprotein. This test is widely applied toward the analysis of large human populations in which interest centers on testing the hypothesis that the distributions of two sub-populations are identical. We suggest that the Kolmogorov-Smirnov test is a preferable method to assess whether differences in distribution of syncytia size between two fusogenic glycoproteins are meaningful statistically.
Three inbred lines of maize (33-16, MO17 and B73) differing in their susceptibility to Barley yellow dwarf virus and Maize dwarf mosaic virus were studied to compare the ultrastructural modifications induced by the two viruses in leaf tissues of different age. The results demonstrate that the alterations induced by the two viruses in the different maize lines could depend on the particular line tested.
The Papanicolaou (Pap) smear has been used to screen women for cervical cancer since 1940. Recently, a number of new technologies have been developed to improve the detection of cervical cancer and its precursors. However, there is substantial controversy about whether the new tests offer meaningful advantages over the conventional Pap smear. Ideally, these new tests will increase the early detection of meaningful Pap smear abnormalities, reduce the number of unsatisfactory smears and provide fewer ambiguous results. It is also hoped that these new screening methods will not increase the number of false-positive results, but will improve the productivity of cytology laboratories without substantially increasing costs. The new tests include liquid-based/thin-layer preparations to improve the quality and adequacy of the Pap smear; computer-assisted screening methods to improve Pap smear interpretation; and new-generation human papillomavirus testing methods that may be useful in triaging patients with atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesions. Evidence on these new tests is reviewed and the advantages and disadvantages of their use are discussed.
